B.o.B. did his time in rap's AAA league, having brushes with success and remaining one or two degrees of separation from household-name status for three years. But that's all over now: His proper debut full-length, The Adventures of Bobby Ray, has been banging out the open car window of every kid with a clue since its April release. B.o.B. has already scored with "Nothin' on You," a song bearing the stamp of approval from both Billboard and the high-horse critics; "Airplanes," featuring Paramore's Hayley Williams, is an even bigger hit. And that success isn't the only thing he shares with Andre 3000 and Kanye West: It might sound ridiculous to call them peers now, but it would not be surprising if that relationship were an unassailable fact by the time fall rolls around.
